Final answer:
Increased operational control through outsourcing is an element for MNEs to consider in the make-or-buy decision.
Step-by-step explanation:
When considering the make-or-buy decision, multinational enterprises (MNEs) should take into account increased operational control through outsourcing. This option allows the company to delegate certain tasks to external suppliers while maintaining overall control over operations. On the other hand, the possibility of offending current customers is not a direct element to consider in this decision. Therefore, the correct answer is b. increased operational control through outsourcing.
